They "played" with the system till they finaly managed to do away with the pump.
I think the key was getting the exhaust to "draw" in enough outside air to light of the cat or alter NOX levels.
I don't know much about that kind of stuff, never had to figure it out, yet...
Anyway, they went from pump to no pump over a few years.
I think the later models just had feed tubes to the exhaust and cat, not the tube manifold into the exhaust manifold.
